v 1927. Serial This invention relates to flush tanks and 1s a divisionof my copendmg appl cation,

Such refill tubes constitute a source of noise which is occasioned bythe friction of the water passing therethrough under varymg pressures.In addition, these tubes as ordinarily constructed 1 constitute a sourceof waste in that a surplus of water is supplied to the bowl andaccordingly wasted.

An object of this invention isto provide a flush tank of suchconstruction and arrangement that the amount of water passing throughthe afterfill or refill tube can be elements removed.

accurately controlled so as to eliminate the friction noises and preventwaste.

This and other objects whichwill be obvious to those skilled in thisparticular art are accomplished bymeans of the invention illus-. tratedin the accompanying drawings in which Figure 1 is a transverse sectionalview througha fiush tank provided with one form of this invention. Fig.2 is a view of a part of the control valve chamber illustrating themanner of connecting the refill tube. thereto I and Fig.3 is atransverse section on the line 3-3 of Fig. 1 with certain of theoperating The particular embodiment of this invention which has beenchosen for the purposes of illustration is shown in conjunction with anordinary flush tank 5 having awate'r sup ply control valve, within thevalve chamber 6, adapted to be automatically operated by the usual float7 and associated mechanism. A refill tube extends from the valve chamberinto the usual overflow tube 21. Hitherto these refill tubes wereprovided with threaded ends which were attached to the valve chamber bybeing threaded into a suitable opening formed therein. The formation ofthreads upon the refill tube, which is of comparatively small gaugematerially weakened it at that point with the resultthat in assemblingthe structureja large loss was sustained through breakage of the refilltubes at their point of connection with the valve chamber. In order toform a more 16,644. Divided and this application filed. June BO. o.202,720.

rugged construction and atthe, same time i provide a device which ismore easily and rapidly assembled, I provide a swivel nut 22 i i I whichis n on the end or the lean tube bv afiange 23 preferably formedon theend'o t the tube. The valve chamberisprovided with a bore 2a extendingthrough the wall thereof and through a lug-'25 formedf-onthe vided withthreads for engagement withthe swivel or coupling nut22 bymeans of whichthe refill tube is connected'to the valve chamber. Such a constructionprovides a rugged structure and enables the refill tube" to be rigidlyconnected to the valve housing in! any adjusted position Without being-sub-. gected to any detrimentalstrain.

The present invention also contemplates the reduction of noise caused bythe friction of water-passing through the refill by con.- 1 v i 6!)outside 01'? the valvexchamber wall and pro-.

trolling theflow therethrougln and italso I contemplates the preventionof a surplus of water flowing through the refill tube wit-h theresulting Waste. As illustrated, this is accomplished by meansoli' a setscrew 26 threaded in a bore 27 communicating with i the opening 24leading from the valve cham ber to the refilltube. A lock nut 28 isprovided for locking the water controlling screw 1n set position. Byproperly positioning the regulating screw 26 the amount of waterfiowingthrough the refill tube can beaconrately controlled so that nosurplus will; pass through to the bowl. In addition, the rate 1 ot flowthrough the tube can be so accurately controlled as to eliminate thefriction. noises which have hitherto also been present. What I claim asnew anddesire tosecure by Letters Patent is:

A flush tank having plvcontrol valve, a threaded lug on the hous- Incombination a 'sup-' ing of said valve, a passage through saidlug to thechamber of saidivalve, a shouldered rehll tube, a couplingnutengagingsaid shoulder and threaded to said lugfor connecting saidrefill tube to said passage and a set screw in said lug for-regulatingthe flow through said refill tube. v i

In testimony whereof, I have hereunto set my hand this 24th day of J1.1118 1 927.
